MAX34440 PMBus 6-Channel Power-Supply Manager
General Description
The MAX34440 is a plex system monitor that can manage up to six power supplies. The power-supply manager monitors the power-supply output voltage and constantly checks for user-programmable overvoltage and undervoltage thresholds. It can also margin the power-supply output voltage up or down to a userprogrammable level. The margining is performed in a closed-loop arrangement whereby the device automatically adjusts a pulse-width-modulated (PWM) output and then measures the resultant output voltage. The powersupply manager can also sequence the supplies in any order at both power-up and...
